SPECIFICATION forming part of Letters Patent No. 689,289, dated December 17, 1901. Application filed February 16, 1901. Serial No. 47,558. (No model.)

T0 all whom t muy concern:

Be it known that I, THOMAS CONWAY, a citizen of the United States, residing at .Kansas City, in the county of Jackson and State of Missouri, have invented a new-and useful Horseshoe, of which the following is a specification.

My invention relates to horseshoes, and more especially to that type embodying removable calks; and my object is to produce a horseshoe of this character which permits of the use in connection therewith of calks of several different styles.

A further object is to produce a horseshoe which possesses the desirable features of simplicity, strength, durability, and cheapness of construction.

Other objects of the invention will hereinafter appeal', and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure l is a perspective, as viewed from the under side, of a horseshoe embodying my invention. Fig. 2 is a cross-section taken on the line II II of Fig. l. Fig. 3 is a section taken on the line V V of Fig. l, but with a modified form of toe-calli in lieu of the form shown in Fig. l. Fig. 4. is a View similar to Fig. 2, but with the calk shown in Fig. 5 in place. Fig. 5 is a view similar to Fig. 3, with a resilient calk. y

In the said drawings, l designates a horseshoe of the usual or any preferred construction as far as its general form and method of securing it to the hoof is concerned, but provided at its toe end with the depending parallel lugs 2, extending longitudinally of the shoe and provided at their rear ends with the inwardlyprojecting shoulders or stops 3. Said lugs are also provided at their front ends with th-e transversely-alined holes 4L and about midway their length with th-e similar holes 5.

My preferred form of toe-calk for winter use comprises a pair of integral arms 6, extending at right angles to eachother and beveled to a point or edge, as at .7, and to secure said calk in place it is arranged with one arm depending and the other projecting rearward .and is` slipped between lugs 2 and against shoulders or stops 3, which llatter ltit snugly against the beveled portion of the horizontal :arm and rin conjunction with the bolts, ex-

,tending through holes 4C of the lugs, and the interposed calk serve to maintain the latter reliably in place, the said shoulders 3, by overcoming any tendency of the calk to move rearward and swing forward, relieving the bolt of strain in a larger measure.- With this form of calk I also prefer to have the lugs 2 beveled to provide rearwardly-converging surfaces 9, (one only of which appears, see Fig. 1,) against which the Aflaring portions of the arms may bear rearwardly to assist shoulders 3 in relieving the bolt of strain.

It is obvious that double wear is obtained from the use of a calk of this type, because when one arm gets dull the position of the calkcan be reversed, so as to cause the sharp arm to depend and the dull arm to tbetween the lugs.

For ordinary service in lieu of sharpenedl oalks, as above described, I prefer to use triangular calks 16. These calks are adapted to t snugly between lugs 2, and the toe-calli is held in position by a transverse bolt 17 extending therethrough and through the lug- Yholes 5, said bolt being relieved largely of strain by the shoulders 3. (See Fig. 3.)

For light work I prefer to employ in lieu of the calks described a calk consisting of a meltallic casing 19, having sloping ends, as at 20, to accommodate shoulders 3, and a resilient body portion 2l, of suitable rubber or rubber composition, this calk being held in position, preferably by a bolt 17 and the shoulders 3, in the manner above described.

Heel-calks of the same type in some particulars as those described are shown; but as the particular construction of these heelcalks has no bearing on the present invention they are not described or claimed.

As the advantages incidental to the use of removable calks and cushioned calks are Well known in the art and, in fact, to the public, it is unnecessary in this connection to point out all of the advantages, direct or indirect, which result from their use, and While I have illustrated and described the preferred embodimentof the invention it is apparent that the construction can be modified in various particulars without departing from the spirit and scope of the invention and that I reserve the right to make all changes which fall below the dignity of invention.

vthe shoe and provided at their rear endswith inwardly projecting shoulders having upwardly and rearwardly sloping front faces, a toe-call: provided at its rear side with a surface extending substantially parallel with the sloping faces of the shoulders, and adapted to fit snugly between said lugs and have its sloping surface engaging said faces of said shoulders, and a bolt to extend through said lugs and the interposed call( to hold the latter in place, substantially as described.

3. A horseshoe, provided with heel-calks, parallel lugs depending from the toe end of the shoe and provided with inwardly-projecting shoulders at their rear ends, and having at their front ends rearwardly-eonverging surfaces, and `a toe-call; to fit snugly between said lugs and aga-inst said shoulders, and provided wit-h sloping su rfaees to bear rearwardly against the rear\\'ardlyeonverging surfaces of the lugs, substantially as described.

4. A horseshoe, provided with heel-callis, parallel lugs depending from the toe end of the shoe and provided with inwardly-projecting shoulders at their rear ends, and a toecall provided with a plurality of arms or tread-surfaces, adapted to t snugly between said lugs and against said shoulders, and a bolt to extend through said lugs and the interposed ealk, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

THO M AS CON W AY.
